Assign Pattern option ( disable or a way to set it )

 I am using the funckey "code below" and now with v16.5 a "Assign Pattern" window is popping up.   I am trying to either set the pattern or disable it completely so my "F" key is more effective.

 Thanks in advance for the reply :)

funckey F "generaledit; prepopup ; pop dyn_option_select 'Selection set@:@Clear all selections' ; set prompt ; prompt 'Enter Ref Des (on next step click pattern to keep it highlighted' ; refdes $prompt ; zoom selection; hilight  ;generaledit "
